Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

  1. In a large pot, sauté the onion, carrots, and celery until softened.

  2. Add the vegetable broth and bring to a boil.

  3. Stir in the peas and asparagus, and simmer for 10 minutes.

  4. Season with salt and pepper to taste.

  5. Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onion
Softens and sweetens as it cooks, building the base flavour of the soup.
Carrots
Add natural sweetness and body while holding their shape during simmering.
Celery
Contributes aromatic flavour and a little texture to the soup base.
Vegetable broth
Forms the liquid that carries flavour and cooks the vegetables through.
Peas
Add sweetness and a tender texture that softens gently in the hot broth.
Asparagus
Adds fresh, green flavour and tender texture when simmered briefly.

The step that matters

Simmer the peas and asparagus. Simmering for too long turns bright green vegetables dull olive and mushy. Ten minutes is enough to cook them through while keeping colour and a fresh taste.

Swap the peas
